having a glow plug problem, they dont seem to last more than about one tank of fuel and i was on number 5 any help?
 
dont forget fuel is coolant as much as it is fuel. you wouldn't run your lawn mower that lean would you?
 
Your too lean that's the only thing that will burn a plug out that fast. Is the filament still in the end of the glow plug after you foul one out? Also it could be your piston hitting the plug if that's the case you need to rebuild the motor but I would try and rich it up a little that should fix your issue. If your running way too rich that will burn one up too but not in one tank.
